Yield maximization and its economics in rice (Oryza sativa L. ) grown during cold season

Abstract

                                Field experiments were conducted for three years (1994-1995 to 1996-1997) during cold season (winter) to find out suitable nutrient management for yield maximization in rice. The growth characters and yield attributes were markedly influenced by the treatments. Application of 20 per cent extra N in addition to 150 50 50 kg N2 P2O2 and K2O ha surpassed other treatments. A fertilizer dose of 180 50 50 kg N2 P2O2 and K2O ha-1 was found best for maximizing the yield of medium duration rice grown during cold season.

Key words : Rice, Cold season, Yield, Economics, Uptake.
